2020 Map of Bannock Pass

About this map

Bannock Pass serves as a critical point on the high ridge line separating the Beaverhead National Forest in Montana from the Salmon National Forest in Idaho. This 2020 map documents the complex topography of the Continental Divide, where the Continental Divide National Scenic Trail winds through high-altitude terrain including Grizzly Hill and Jakes Canyon. The map reveals a network of primitive roads and trails that follow the natural drainage patterns of the Bitterroot Range, such as Railroad Canyon Rd and S Divide Creek Rd. Significant water sources are named throughout the high country, including Irish Boy Springs, Wagonbox Springs, and the headwaters of Horse Prairie Cr. The presence of the Nez Perce Nht (Nez Perce National Historic Trail) in the northeast corner highlights the area's deep connection to Indigenous travel routes across the divide.
